Hi and welcome to the forum.
Hope you don't mind me mentioning but your post has applied a 'scatter gun' approach who is a bit confusing.
It's much better to post a specific question, Also this post is in 'look-ups' rather than the probably more effective 'Soldiers';
had you posted there it would first have directed you to the parent site, the Long Long Trail where there is lots of advice http://www.1914-1918...dad/grandad.htm
For example Bernard Lane was probably wounded or became sick while serving with the Devon Regiment and after transfer to the Labour Corps did not serve overseas and 'died' implying sickness, the other categories are killed in action or died of wounds.
You should look at the CWGC site which will tell you where he was buried, often local newspapers gave extensive coverage to funerals at home.
Then again there are experts on Conscientous Objectors or the Yeomanry who will miss your post because of the catch all title and so on
People are willing to help but need to know what you're looking for.
